The statistical tool that primarily notices trends between two variables is the **correlation coefficient**. The correlation coefficient measures the strength and direction of the linear relationship between two variables.
The **Pythagorean theorem** is a mathematical principle related to right triangles, and the **t-test** is used to compare the means of two groups. Therefore, they do not specifically measure trends between two variables like the correlation coefficient does.
